Does Invoking One's Sixth Amendment Right to An Attorney Also Imply Invoking One's Fifth Amendment Right ?

In McNeil v. Wisconsin, 501 U.S. 171, 115 L. Ed. 2d 158, 111 S. Ct. 2204 (1991), the defendant invoked his sixth amendment right to counsel at his bail hearing for an armed robbery offense. McNeil, 501 U.S. at 173-74, 115 L. Ed. 2d at 165, 111 S. Ct. at 2206. Later, investigators questioned the defendant about an unrelated murder after providing the defendant with his Miranda warnings. McNeil, 501 U.S. at 173-74, 115 L. Ed. 2d at 165, 111 S. Ct. at 2206. The Supreme Court discussed that the sixth amendment right to counsel is offense specific and cannot be invoked for all future prosecutions; the fifth amendment right to counsel pertains to custodial interrogations about any matter. McNeil, 501 U.S. at 175-77, 115 L. Ed. 2d at 166-68, 111 S. Ct. at 2207-08. "The purpose of the Sixth Amendment counsel guarantee--and hence the purpose of invoking it--is to 'protect the unaided layman at critical confrontations' with his 'expert adversary,' the government, after ' the adverse positions of government and defendant have solidified' with respect to a particular alleged crime." McNeil, 501 U.S. at 177-78, 115 L. Ed. 2d at 168, 111 S. Ct. at 2209, quoting United States v. Gouveia, 467 U.S. 180, 189, 81 L. Ed. 2d 146, 155, 104 S. Ct. 2292, 2298 (1984). The purpose of the Miranda-Edwards guarantee, the Court explained, is to protect the defendant's interest in dealing with the police only through counsel. McNeil, 501 U.S. at 177-78, 115 L. Ed. 2d at 168, 111 S. Ct. at 2209. Thus, the Court held that invoking one 's sixth amendment right to counsel for assistance during prosecutorial proceedings does not impliedly invoke one's fifth amendment right to counsel during interrogations about any matter. McNeil, 501 U.S. at 179-80, 115 L. Ed. 2d at 169-70, 111 S. Ct. at 2209-10.
